r - 有时命令在升级到 R 4.0 和 Ubuntu 20.04 后不会终止

Answer 1

The solution was provided via r-sig-debian mailing list by Dirk Eddelbuettel and Sébastien Villemot.

I don't know if this is necessary, but I first did:

sudo update-alternatives --config libblas.so.3-x86_64-linux-gnu

and select /usr/lib/x86_64-linux-gnu/blas/libblas.so.3 (instead of pthread).

Then (this worked):

sudo apt install  libopenblas-openmp-dev
sudo apt remove libopenblas-pthread-dev libopenblas0-pthread
